GENERAL DESCRIPTION ADG3123BRUZ

The ADG3123 is an 8-channel, noninverting CMOS to high voltage level translator. Fabricated on an enhanced LC2 MOS process, the device is capable of operating at high supply voltages while maintaining ultralow power consumption.

The internal architecture of the device ensures compatibility with  logic circuits running from supply voltages within the 2.3 V to  5.5 V range. The voltages applied to Pin VDDA, Pin VDDB, and  Pin VSS set the logic levels available at the outputs on the Y side  of the device. Pin VDDA and Pin VDDB set the high output level  for Pin Y1 to Pin Y6 and for Pin Y7 to Pin Y8, respectively. The  VSS pin sets the low output level for all channels. The ADG3123  can provide output voltages levels down to −24.2 V for a low input  level and up to +35 V for a high input logic level. For proper  operation, VDDB must always be greater than or equal to VDDA  and the voltage between the Pin VDDB and Pin VSS should not  exceed 35 V.
